In the Account Control Center, you can teleport your realm to a different randomly-chosen sphere.
You may do this up to 3 times per round. Your old
sphere's news will show that you have teleported but not your destination.
Teleporting has the following costs:
5% of your land will be lost.
10% of your gold will be lost.
10% of your mana will be lost.
10% of your peasants will be lost.
5% of your military units will be lost.
